-===== Ubuntu Workstation Basic Setup =====
+====== Workstation ======
+  * Ubuntu workstation basic setup
+===== BIOS =====
-==== BIOS ====
   * before installing Ubuntu, power on the workstation, enter the BIOS setting, and update the boot setting. CD/DVD-ROM should be listed as the 1st choice, following by the hard drive for Ubuntu installation
+===== Ubuntu =====
+   * Use the latest long-term support (LTS) version
+   * Install the system on the smaller/faster SSD; use the larger/slower HDD for '/backup' and/or '/scratch'
-==== Network ====
+===== SSH =====
-    * The system administrator requires the HWaddr of the Network Interface Controller (NIC) to add the new machine to the DHCP server.
-    * In Terminal, type "ifconfig" to get the HWaddr of eth0 (format = XX:XX:XX:XX:XX:XX). Write down this string and send it to the administrator.
-    * After the DHCP server setting has been updated, restart the computer to obtain the correct intranet IP.
-    * Note: this only has to be done once (no need for re-installation unless the Network Interface Controller has been changed)
-==== Ubuntu v14.04 (2015/01/07) ====
-   * Basic installation
-     * Put the Ubuntu14.04 DVD into the DVD-drive.
-     * Restart the computer and boot the computer through that DVD.
-     * Follow the instruction to install Ubuntu.
-     * hard drive partition:
-       * use the SSD as the primary hard drive
-         * SWAP >= the size of RAM
-         * the remaining part could be mounted as root ('/') and used for OS installation
-       * the larger/slower hard drive could be mounted as '/backup'
-==== SSH ====
   * Install the OpenSSH server
     * The OpenSSH client is installed by default (so you can ssh into other computers). The OpenSSH server is required for connection into this machine (e.g., auto backup from the lab server). Use ''sudo apt-get install openssh-server'' to install.

      * Minimally, update the ''/etc/hosts.deny'' and ''/etc/hosts.allow'' files to allow only the IPs that should have access
      * Install Fail2ban: ''sudo apt-get install fail2ban''
